At prom time this year, teens will be doing all they can to keep up with the Kardashians — by spending Hollywood-level wads of cash to put some glamour in their big night.

From double-decker Hummer party buses to designer dresses to Hamptons weekend getaways, there’s no limit to what some high-schoolers will pay.

“This year, kids are spending wedding prices for proms,” said Rashi Pinckney, manager of Oz Boutique in Forest Hills, Queens. “Everyone wants to be Kim Kardashian or Lady Gaga. It’s increased by $500 since last year.”

Alessandra Asperti, a senior at College of Staten Island HS, will spend roughly $1,500 on her big night.

“I’ve been saving up since my sweet sixteen,” said the 18-year-old dancer.

Some teens are trying to buy the exact designer dresses celebrities have worn.

Big sellers are the strapless Jovani gown which Taylor Swift wore on her “Fearless” tour, and the rhinestone-studded white Sherri Hill dress Selena Gomez rocked at a recent concert.

“It’s kind of sweet to know that celebrities are wearing dresses that girls traditionally wear to prom,” said Gina Kelly, fashion director of Seventeen Magazine. “[Buying one] may cost $1,400 and it’s expensive. But it’s possible.”

And the dress is just one element of the evening.

“These kids have taken it to a new level,” says Jon Liney, founder of dressgoddess.com. “Everything is taken into consideration, from dress to tanning to hair to after-prom. They don’t skimp on anything.”

Christina Ornes, a senior at St. Mary’s in Manhasset, LI, will be heading to a Hamptons mansion after her prom with 25 other students — at $250 a pop.

“It’s my senior prom and it only happens once in a lifetime,” she said. “I have no budget.”

The traditional white limo is a thing of the past, too. Now, it’s a $9,000-a-night double-decker Hummer equipped with stripper poles.

“There’s a long waiting list,” said Kenny Caldwell, owner of Designer Limousine.

But not everyone loves the new trend.

“It’s absurd and it’s sad,” said Sally Greenberg, executive director of the National Consumer League. “It’s a waste of precious resources that they should be using to pay for college.”
